How many extra 2x4s have you purchased just to support long molding strips or pipe during the ride home from the store? Jason Knisely of Yukon, Oklahoma, (via e-mail) cut a 12-ft. 2x4 to fit inside his truck bed and then reattached the remaining piece with a hinge. He added two barrel bolt latches to the sides opposite the hinge to keep the 2x4 support extended when in use. Jason leaves the folded 2x4 in his truck bed so itís ready to take on a supporting role at any time
